FIRELESS BROODER.

To au whom @'25 may concern.'

Be it known that l, NiuLs PETER BRODER- sEN ELLEGAARD, a subject et the King of Denmark, residing at Petaluma, in the county of Sonoma and State of California, have invented certain new and useful lmprovements in Fireless Broeders; and I do declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tireless breeders.

One object of the invention is to provide a broeder of this character having an improved construction and arrangement of compartments to receive the chicks and compartments to contain a heating medium whereby a uniform heat will be maintained in the broeder for a considerable length of time and will be discharged into the chick compartment above or over the chicks, thus supplying the heat in a natural manner as the same would be supplied were the chicks brooded by a hen.

Another object is to provide a broeder having an adjustable top or hover adapted te be raised and lowered and supported at different elevations in the chick compartment et' the broeder and having an adjustable means for preventing the chicks from crowding one another.

With these and other objects in view, the invention consists of certain novel features et construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l is a perspective view of my improved broeder; Fig. 2 is a vertical cross sectional view taken on the line 2 2 et Fig. 1; Fig. 3 is a similar view taken at right angles to Fig. 2 and on the line 3 3 of Fig. 1; Fig. d is a plan View of the broeder with the top or hover removed, and parts broken away and in section. Fig. 5 is a vertical sectional view taken diagonally through the broeder on the line 5 5 of Fig. 4; Fig. 6 is a detail bottom plan view of a portion of the hover or top of the chick compartment et the broeder; Fig. 7 is a detail perspective View of the adjustable partition for the chick compartment; Fig. 8 is a cross sectional view of the partition taken on the line 3 8 et Fig. 7; Fig. 9 is a detail perspective view of one of the removable cover pieces for the Specification of Letters Patent.

compartment which contains the heating medium oit the broeder.

My improved broeder comprises an outer casing l which'may be of any suitable size and shape and is here shown as being square or rectangular, and in one side of which is formed a door opening 2 adapted to be closed by a vertically moving door 3 which is slidably supported in suitable guides l secured to the outer side et the casing. The door is provided with a series et Ventilating openings or perforations 5 through which air is supplied to the chicks as will be hereinafter more fully described. In the casing 1 is arranged a circular partition 6 between which and the inner sides and corners of the casing is formed a space 7 adapted to receive het sand or other heating medium whereby the broeder is heated. The ends oi the partition 6 opposite the door opening 2 in the side et the casing are bent radially' to form a passage 8 leading to the central compartment of the broeder within the partition 6 and in which the chicks are received.

The space 7 between the partition 3 and the sides ot' the casing is closed by a top o1' upper wall 9 and in each cerner of said top 9 is formed a triangular opening 10 through which the sand or other heating medium is supplied to the space 7. rlhe openings 10 are closed by tri angularly shaped cover pieces 11 which are supported on cleats 12 secured to the inner sides of the easing. In each of the cover pieces 11 is a Ventilating opening 13 in which is secured a tab 14 by means of which the cover piece may be readily removed and replaced in the openings 10. In the sides of the casing at a suitable distance above the bottom thereof are formed Ventilating openings 15 which permit some of the heat to escape from the space 7.

Arranged within the central space or chick compartment l@ adjacent to and spaced a suitable distance from the inner side or the circular partition (i is a circular guard and heat deflect-ing plate 1 7 which extends upwardly to substantially halt the height of the broeder and is spaced a slight distance from the partition G by spacing strips 18 as clearly shown in Fig. e et the drawings. In the lower portion et the partition 6 are formed series of triangular-ly shaped heat passages 19 through which the heat from the material placed in the compartme-nt er space 7 passes upwardly between the partition and the guard plate 17 and is discharged into the upper portion ot the compartment 16 over the chicks thus supplying the heat to the latter in a natural manner or in the same manner in which the heat would be supplied by a hen in covering the chicks. The space or compartment 16 is preferably divided into two compartments by a transversely disposed partition 2O which is pivotally and adjustably supported in the compartment by a centrally disposed stud 21 which is adapted to be enu gaged with a series of vertical sockets QQ formed in the bottom of the casing as shown in Fig. L1 o' the drawings. rlChe main portion oit the partition 2O is considerably shorter than the diameter of the compartment 16 and on the upper and lower edges of the ends of the partition are formed guide flanges 23 with which are slidably engaged plates Qd adapted to be shifted inwardly and outwardly in the anges 23 to regulate the length ot' the partition according to the position in which the saine is adjusted in the compartment 16 as clearly illustrated in full and dotted lines in F ig. L1 of the drawings. By providing the partition 2() as herein shown and described the chick compartment may be divided into two spaces to prevent the chicks from crowding and injuring each other,

Arranged in the upper portion of the chick compartment of the brooder is a circular cover or top 25 which is adjustably supported in said compartment by pins 26 which are engaged with vertical series or" pin holes 27 formed in the partition 6 and in posts 28 which are secured to the bottom of the casing and which serve as braces for the partition 6 and as supports for the top 9 orn the space 7. Secured to the inner side of the top or cover 25 are series ot telt strips 29 which depend or hang down in the chick compartment and together with the top 25 form a hover for the chicks. rhe telt strips Q9 may be secured to the inner side of the top 75 in any suitable manner but are preferably secured thereto by a series of transverse cleats 30 which are fastened to the inner side ot the cover by screws whereby said cleats and the felt hover strips may be quickly and easily removed to permit the strips to be cleaned or renovated. ln the top 25 are formed a series of ventilating openings 31 each of which is provided with a pivoted cover plate 32 which is adapted to be swung over the upper ends of the openings to a greater or less extent thereby regw ulating the size of the same and controlling the ventilation of the chick compartment. Secured to the upper side of the cover or top 25 is a transverse cleat or cross bar 38 to which is secured a centrally disposed handle 34 whereby the top or cover may be readily removed when desired.

By providing a series of felt hover strips as herein shown and described the heated air discharged over the heat detiect-ing plate 17 will circulate through or between the depending ends of the hover strips and will thus be evenly distributed to all of the chicks beneath said strips.

lVhile I have herein shown and described the space 7 between the partition 6 and the sides of the casing as being provided to receive sand or other heating medium this space may also be employed for containing a volatile disinfectant or insecticide., the fumes of which will be discharged into the chick compartment in the same manner in which the heat passes thereto. By placing the disinfectant or insecticide in the space 7 the chicks cannot reach the same which will permit the use of eitective poisons which cannot be otherwise employed for disinfecting the brooder or keeping the chicks free from vermin.

lrom the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacriicing any of the advantages of the invention as claimed.
